ATTACHMENT FOR REPAIR-TOOLS.

Specification of Letters Patent,

Patented Apr. 12, 1910.

Application filed October 24, 1908. Serial No. 459,335.

To all whom it may concern:

Be it known that I, WINFIELD L. DINs- MOOR, a citizen of the United States, and a resident of Longbeach, in thegcounty of Los Angcles and State of California, have inroved Attachment for Repair-Tools, of which the following is a full, clear, and exact description.

The invention is an attachment for repair tools, more especially a tool of the nature disclosed in Patent No. 877,306, granted to me January 21, 1908, and is designed to provide a heating plate for vulcanizing pur poses, interchangeable with the upper or movable clamping plate on the said tool.

To this end the heating plate is preferably .cast with an inner chamber or passages and has one or more burners on its outer face communicating with said passages, shields over the burners for reflecting the heat to the plate, and a lug or seat for the reception of 'the clamping screwwhich operates to force the two jaws or clampinlg plates together. In automobile repair wor the gas for the burner is let into the supply assages ordinarily through the burner handle, and if the repair is made on the road, the supply of gas is had from the acetylene generator.

Reference is to be had ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. 4

Figure 1 illustrates in cross-section, my improved attachment as applied to my patented repair tool; Fig. 2 is a section through to the accompanythe same at right-angles to the section in Fig. 1.; .and Flg. 3 is a perspective view illustrating the mode of use of my improvements.

In order that a full understanding of the manner in which my improved repair tool attachment is used, I have shown it in connection with the repair tool above referred to, the same consisting of a clamping member or plate 10 having a vise 11 at one side, a yoke 12 at-the opposite side, hinged to. the under side of the plate 10, and a clamping screw 13, which ordinarily carries a clamping member or plate (not shown), coactin with the plate 10. The screw-operated with my improved attachment, which is also in the nature of a plate 14, of like extent, having a chamber or passages 15. with burners 16 of the late and ribs W rich are side of the center of the plate and covered by shields 17 which serve to reflect the heat inwardly. One end of the plate has a thermometer 18 let into its edge, and at the 0pposite end a cook or cation with a tubular handle 20, connects with the chamber or passages leadin to the burners. The connection between tie cock 19 and the tubular handle is elfected by providing the bore of the handle with a tube 21 which is extended beyond the outer end of thehandle in the form of a nipple 22 for the connection of a rubber tube or other similar device in piping the gas to the burners, this gas ordinarily being supplied from the acetylene enerator for the automobile lamps, especia l-y when the repair is made on the road where cit gas is not obtainable. The outer face of tie plate 14 is provided at its center with a seat for the inner end of the clam ing screw 13, which, in order to insure a sat cient thickness of metal over the longitudinal passage 15, is in the nature of a lug 23 having a central recess.

In vulcanizing a patch to the inner tube of a tire without entirely removing it from the vehicle wheel, the repair tool is applied as illustrated in Fig. 3, the usual upper clamping plate being supplanted with my improved heating plate. After the attachment has been connected with the gas supply the valve 19 is turned on and the burners ighted. When the temperature of the plate rises to the required point as indicated on the thermometer 18 (ordinarily 275 Fah. for vulcanizing), the patch is pressed firmly to the tire by the plate upon operating the screw 13.

Although I have shown my attachment in connection with a particular form of repair tool, it is evident that it may be advantageously used as one of the clamping plates 'or members of any clamp. Having thus described my invention, I claim as new and desire to secure by Letters Patent: 1. A ortable vulcanizing tool comprising a plate aving a vuloanizing face at one side and a face at the'opposite side accessible for clamping the plate to the part to be vulcanized, said plate provided with a gas or va- 'valve 19, in communipor burner arranged to heat the Vulcanizing face, and a handle extending outwardly from'the edge of the plate between the two faces, having a gas supply passage leading to the burner.

2. The combination of a clamping plate, a second clamping plate coacting therewith, having a burner on its outer face and provided with a gas supply passage leading to the burner, and a shield over the burner, arranged to reflect the. heat downwardly on the plate.

3. The combination of a clamping plate,- a vulcanizing clamping plate having burners and provided with a passage therein leading to said burners shields arranged over the burners to reflect the heat downwardly on the plate, and'means to force the plates together.

4:. In a repair tool, a clamping-plate having means to detachably secure it to the rim of a vehicle wheel and extend to one side thereof, a vulcanizing clamping-plate having a burner, and means carried by the first mentioned clampingplate to force the vulcanizing clamping-plate thereto.

5. In a repair tool, a clamping plate having means to detachably secure it to and support it on a vehicle wheel and provided with a clamping screw, and a vulcanizing clamping plate removable at will between the screw and the first mentioned clamping plate and having a heating burner.

6. In a repair tool, a clamping-plate having cle wheel and provided with a clampingsorew, and a vulcanizing clamping-plate removable at will between the screw and the first mentioned clamping-plate and having a heating burner.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
